Cops in riot gear stormed a building Saturday, searching for a gunman who shot and killed a college student during an early-morning argument near Gravesend, Brooklyn.
Allen Tahiraj, 19, died after being shot in the chest as he hung out with friends on Ocean Parkway about 3:30 a.m., police said.
"There was a little argument and one of the kids pulled a gun," said Chris Mayer, a friend of the victim's. "[Tahiraj] tried to pull it out of his hand."
Witnesses said the gunman, believed to be in his 20s, ran into a building on Ocean Parkway near Avenue P, sending dozens of police in helmets and riot gear pouring into its hallways.
As portions of the building were evacuated, police brought in a tanklike armored vehicle, ropes, battering rams, drills, cameras and other equipment. All traffic was halted for several blocks north and south on the parkway.
